Common Name Adriana's Masdevallia [Mrs Sijm Dutch wife of orchid enthusiast, cultivator of species]

Flower Size 3/4" [2 cm]

Found in central Ecuador without locality as a mini-miniature sized, presumed caespitose epiphyte with erect ramicauls enveloped by 2 to 3, loose, tubular sheaths and carrying a single, apical, erect, coriaceous, elliptical, subacute, cuneate below into the petiolate base leaf that blooms on a slender, arising from low on the ramicaul, suberect, sharply triquetrous, 6 to 7.6" [15 to 19 cm] long, congested, successively several flowered inflorescence with a bract near the base and imbricating, shorter than the pedicel floral bracts.

"The flowers are produced successively in a congested raceme borne by a slender, triquetrous peduncle that exceeds the leaf in length. The sepals are deeply connate into an orange tube that is obtusely swollen on the bottom side. With recurving margins, the dorsal sepal forms a tube-like tail beyond the sepaline tube. The lateral sepals are suffused with red-purple and are connate to within .2 " [5 mm] of the subacute, tailess apices. The petals are oblong and longer than the lip that is divided above the middle by marginal folds." Luer 2000
